Abstract. A method of synthesis and analysis of control algorithms based on fuzzy logic and neural networks is presented. A two-mass electromechanical system with a nonlinear perturbation in the form of a dry friction torque is used as an example. Behavior of the synthesized system under the influence of the wind torque is studied. Robustness of the systems with variation of the second mass inertia as a parametric disturbance is analyzed. The analysis of the obtained results allows to estimate the expediency of application of the considered algorithms.
Keywords: electric drive, fuzzy logic, ANFIS, neural networks, robust control, position control
